Sony Ericsson Mobile Phone Unlocking

To connect phone in flashing mode, and perform tasks like flashing the main firmware, FS or to upload files to FS you must have USB Flash drivers installed on your computer.

With out installing USB Flash drivers, you can’t use XS++ or SeTool 2 lite or JDFlasher.

In good old days we used to use SEUS to do this automatically for us, but now SEUS updates phone to CID53 which is not desirable, so hence we install USB Flash Drivers manually. Here is the tutorial ! Please read the tutorial completely and also check out the video attached !

Then unpack the downloaded archive to a directory, your choice. (Use WinRAR to extract from archive)

1. Switch OFF your phone !

2. Remove the battery !

3. Reinsert your battery !

4. Don’t start your phone !

5. HOLDING ‘C’ on your phone, connect your phone to USB Cable !

6. Don’t Leave C through out driver installation.

You get a notification in System Tray ! Saying SEMC USB Flash Device

A new window should appear “Found new hardware wizard”

It asks permissions for to search for drivers for the device. Select “No, not this time” and click next.

Then select the option INSTALL FROM A SPECIFIED LOCATION(ADVANCED) and click next

Then choose “Search for the best drivers in these locations”, and check the “Include this location in this search”, now browse for the downloaded drivers.

Click next, Wait for some time, drivers get installed.

Now…….

Open the directory, where you unpacked the archive, In the directory, you will find a ggsemc.inf file. Click on it with the right mouse button, and then click ‘Install‘.

Here we discuss how to flash the firmware. Also debranding a phone is flashing the phone with a generic main and a generic FS of your region

SE phone Firmware has two parts.

Main Firmware which contains all the phone software. Main firmware file has the .mbn extension.

FS is a firmware which has settings and all other data like the default Images and Ringtones and all other files that is used by phone. It has .fbn file extension.

Before you flash the main firmware make GDFS BACKUP. GDFS backup is very important and not to be missed.

The video Shows how to flash the firmwares. Watch the video tutorial.

Now some important information

In this video a w610 firmware is flashed to a k550. But you must use the firmware of your phone, if your phone is a k810 then use k810 firmwares. But if your phone is S500 then you can use either S500 Firmwares or W580 Firmware, etc.

For debranding its necessary to flash both main and fs.

Only the Main can be flashed. Not a problem. But its always recommenced to flash FS also.

Many FS are available for a phone, you must choose the FS that has your language files

By default all FS have English langauge.

You can download FS and Main from TOPSONY. Or for free from TOPSE if the FS for your area is available. Or you can make a request at se-nse firmware section. People those who have the firmware should help you. Also check out my download section for few links.

If you are flashing the FS then you must also do customization or flashing of CDA. If you don’t do then phone won’t start. Your phone will halt boot saying configuration error. To do this you must download Custpack from se-nse download area. And flash them using own_custpack method which is shown in the video as well.
